Block diagram
The analog interface handles the modulation and demodulation of the analog signals.
The contactless UART manages the protocol requirements for the communication
protocols in cooperation with the host. The FIFO buffer ensures fast and convenient data
transfer to and from the host and the contactless UART and vice versa.
Various host interfaces are implemented to meet different customer requirements.
